Science Buddies: "Ask an Expert"

Need help!! Having trouble finding websites with information on the density and buoyancy of watermelons, peaches, grapes, tomatoes and limes. Need direction!!!! This is for my 4th gade science fair!!!

Hi malfitano,

The standard web search site is google.com

I tried out some searches and simpler searches seemed seemed to be better. So, you can do ten searches, with each of the lines below as input to google.com:

watermelon density
peach density
grape density
tomato density
lime density
watermelon buoyancy
peach buoyancy
grape buoyancy
tomato buoyancy
lime buoyancy

You can copy/paste each of the lines above to save some typing.

Two other search sites are ask.com and answers.com

Before doing the ten searches on google.com, you may want to try some of the searches on ask and answers to see if they are giving better results.

By the way, please excuse if this is what you were already doing.

Hello, malfitano!

Direction for a science fair project is usually easy when we have a question to investigate or a hypothesis to prove. For example, we might decide that the question is, "Which if the following fruits have the greatest buoyancy in water: watermelons, peaches, grapes, tomatoes and limes?" You could then have direction in setting out to design an experiment to test that. If you find the density information you are looking for you could augment the experiment by predicting the winner. Your experiment would then be proving the reference data.

I recommend that you come up with a question to answer or a hypothesis to prove in order to provide direction for your project.

Best wishes for success!

Hi malfitano,

Another approach is to do a more general search, using "fruit" rather than a specific fruit.

A search on "calculate fruit density" leads to:
http://web.wm.edu/act2online/Lesson_Pla ... _fruit.htm
The above references work that was done in fifth grade.

A search on "calculate fruit buoyancy" leads to:
http://morrisonlabs.com/densitystandards.htm which covers both density and buoyancy.
